DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Small Community Leads Central Florida In Potable Water Reuse Implementation

  Altamonte Springs’ implemented a pilot program called the pureALTA project with two primary goals – to serve as platform for future potable water reuse efforts; and to educate the 45,000 residents about the benefits of potable water reuse.

• Indiana American Water Eliminates Gaseous Chlorine At Hidden Lake WTP In Warsaw, Indiana

  In 2000, Indiana American Water, a subsidiary of American Water Company, purchased the Warsaw Indiana system which serves a population of over 16,000. Indiana American then completed a Comprehensive Planning Study that included a number of upgrades and improvements to enhance the reliability, safety and water quality of the system.

• Retrofitting Water Systems With The Best Meters For The Job

  Although not every water, wastewater, or industrial design engineer or operations manager is familiar with the advantages of the V-Cone differential-pressure (DP) meter design, they are certainly familiar with the problems it can solve. Here is a step-by-step description of how V-Cone meters with + 0.5 percent accuracy offer better alternatives in applications currently being failed by other metering technologies.

• What Your Chlorine Residual Is Trying To Tell You

  We look at what your chlorine residual monitoring data is trying to tell you - and provide brief explanations on the subject.

• A Pilot Study Involving Three Different Treatment Media (Loprest)

  As part of a feasibility study for arsenic treatment at an elementary school in California, a pilot study was conducted to test the performance of three different treatment media: (1) greensand and anthracite, (2) standard sand and anthracite, and (3) manganese dioxide.

• Encore® 700 Chemical Metering Pumps Provide Precise Coagulant Metering

  Water utility operators are increasingly challenged by scrutiny and regulation on disinfection by-product (DBP) levels while trying to manage ever increasing coagulant costs in a tight budget environment.

• Managed Metering Solutions Offer A Strong Business Case

  Many municipalities would benefit from a managed solution for water meter reading. However, they often avoid a deep dive into the option after performing a cursory, and flawed, cost-benefit analysis. When properly evaluated, managed solutions frequently provide a better and more viable alternative.

• Smart Meters With Integrated Valves Promote Long-Term Savings

  Picture this common scenario for a water utility: A past due account triggers multiple notices to a home, but with no response from the customer, a crew is sent to shut off service. Throughout the process, the municipality racks up other labor costs, including personnel needed to create the work order and a return visit by a crew to restore service once the account is current.

• Gulf Of Mexico's Hypoxic Zone Larger Than Ever

  Last year, the National Oceanic and Atmospheric Administration (NOAA) recorded the largest hypoxic zone in the Gulf of Mexico since monitoring began 32 years ago. Hypoxic waters, often referred to as dead zones, have dissolved oxygen concentrations of less than 2-3 ppm. They are caused by eutrophication or excess nutrients that promote algal growth in water bodies. As algae decompose, they consume oxygen creating dead zones.

• Seawater Desalination Using RO Membranes To Support A Thriving Agricultural Economy

  As the agriculture economy boomed, needs for freshwater demanded by irrigation, tourism and the local community also grew in Campo de Dalías, a coastal region on the Mediterranean Sea. As a result, the region faced overexploitation of groundwater aquifers. Read the full case study to learn how Toray was selected as the sole membrane supplier for a two-pass system for a newly implemented national desalination plan.
